“…A reddish coloration of the lagoon surface, suggesting the presence of PSB populations, generally developed during the summer and fall (Table 2). The lack of reddish appearance of the lagoon until midsummer (approximately DOY 180) suggested that PSB populations declined during the winter [18] and may have slowly rebuilt during the spring [5,7]. The reddish surface color of the lagoon was assumed the best indicator of significant PSB populations.…”

“…This coloring is usually a result of the presence of large populations of purple sulfur bacteria (PSB) from the family Chromatiaceae in the phototrophic regions of the lagoon. These bacteria can photosynthesize anoxygenically and oxidize H 2 S rising from the lower reaches of the lagoon to SO 4 2− [5,6], consequently reducing emissions from the lagoon surface [7,8]. The optimal pH for PSB ranges from 7.5 to 8.2 [7].…”

The optimal pH for PSB ranges from 7.5 to 8.2 [7]. Purple non-sulfur bacteria (PNSB) have also been found in swine lagoons but are unable to oxidize zero-valent sulfur to sulfate and hence have a competitive disadvantage in a HS --rich anaerobic lagoon [5].…”

Hydrogen sulfide (H2S) from hog operations contributes to noxious odors in the surrounding environment and can be life-threatening. There is, however, limited understanding of what influences H2S emissions from these farms. Emissions of H2S were measured periodically over the course of two years at hog finisher farms in humid mesothermal (North Carolina, NC, USA) and semi-arid (Oklahoma, OK, USA) climates. Emissions were determined using an inverse dispersion backward Lagrangian stochastic model in conjunction with line-sampled H2S concentrations and measured turbulence. Daily emissions at the two lagoons were characterized by low emissions on most days with occasional days of high emissions. Mean annual area-specific emissions were much lower for the NC lagoon (1.32 µg H2S m−2 s−1 ± 0.07 µg H2S m−2 s−1) than the OK lagoon (6.88 µg H2S m−2 s−1 ± 0.13 µg H2S m−2 s−1). Mean annual hog-specific emissions for the NC lagoon were 0.75 g H2S hd−1 d−1 while those for the OK lagoon were 1.92 g H2S hd−1 d−1. Emissions tended to be higher during the afternoon, likely due to higher mean winds. Daily H2S emissions from both lagoons were greatest during the first half of the year and decreased as the year progressed and a reddish color (indicating high populations of purple sulfur bacteria (PSB)) appeared in the lagoon. The generally low emissions at the NC lagoon and higher emissions at the OK lagoon were likely a result of the influence of wind on mixing the lagoon and not the presence of PSB.

There are two main types of bacterial photosynthesis: oxygenic (cyanobacteria) and anoxygenic (sulfur and non-sulfur phototrophs). Molecular mechanisms of photosynthesis in the phototrophic microorganisms can differ and depend on their location and pigments in the cells. This paper describes bacteria capable of molecular oxidizing hydrogen sulfide, specifically the families Chromatiaceae and Chlorobiaceae, also known as purple and green sulfur bacteria in the process of anoxygenic photosynthesis. Further, it analyzes certain important physiological processes, especially those which are characteristic for these bacterial families. Primarily, the molecular metabolism of sulfur, which oxidizes hydrogen sulfide to elementary molecular sulfur, as well as photosynthetic processes taking place inside of cells are presented. Particular attention is paid to the description of the molecular structure of the photosynthetic apparatus in these two families of phototrophs. Moreover, some of their molecular biotechnological perspectives are discussed.

“…Previously, we showed that cytochrome c′ (PHCP) from thermophilic Hydrogenophilus thermoluteolus growing optimally at 52 °C had a denaturation temperature of 87 °C, which was higher than that of the mesophilic homologue (AVCP, 53 °C) from Allochromatium vinosum growing optimally at 25 °C [5][6][7][8]. X-ray crystal structure and analytical centrifugation analysis indicated that PHCP (PDB ID; 5B3I) was a dimeric protein similar to AVCP (PDB ID; 1BBH) [9,10].…”

AVCP cytochrome c' from mesophilic Allochromatium vinosum exhibits lower stability than a thermophilic counterpart, Hydrogenophilus thermoluteolus cytochrome c' (PHCP), in which the six specific amino acid residues that are not conserved in AVCP are responsible for its stability. Here we measured the stability of AVCP variants carrying these specific residues instead of the original AVCP ones. Among the six single AVCP variants, all of which formed a dimeric structure similar to that of the wild-type, three were successfully stabilized compared with the wild-type, while one showed lower stability than the wild-type. In addition, the most stabilized and destabilized AVCP variants could bind CO, similar to the wild-type. These results indicated that mesophilic AVCP could be stabilized through specific three mutations modeled by the thermophilic counterpart, PHCP, without changing the CO binding ability.
